For the High Rip Current Risk, dangerous rip currents. * WHERE...South and west facing reefs of Guam and Rota. * WHEN...Until 4 AM ChST Monday. * IMPACTS...Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water. * ADDITIONAL DETAILS...As Super Typhoon Champi continues moving away from the region, surf has fallen below life-threatening levels but will remain hazardous at least through tonight. In addition, storm- induced coastal inundation and significant coastal erosion are no longer expected. Even so, minor wave run-up can still occur. Rip currents will be life threatening. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Rip currents will be life threatening. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
